Effect of ambient fine particulates (PM2.5) on hospital admissions for respiratory and cardiovascular diseases in Wuhan, China

open access: yesRespiratory Research, 2021
Background Positive associations between ambient PM2.5 and cardiorespiratory disease have been well demonstrated during the past decade. However, few studies have examined the adverse effects of PM2.5 based on an entire population of a megalopolis.

Finite size scaling in crossover among different random matrix ensembles in microscopic lattice models

open access: yes, 2013
Using numerical diagonalization we study the crossover among different random matrix ensembles [Poissonian, Gaussian Orthogonal Ensemble (GOE), Gaussian Unitary Ensemble (GUE) and Gaussian Symplectic Ensemble (GSE)] realized in two different microscopic ...

Dynamics of Shock Probes in Driven Diffusive Systems [PDF]

open access: yes, 2007
We study the dynamics of shock-tracking probe particles in driven diffusive systems and also in equilibrium systems. In a driven system, they induce a diverging timescale that marks the crossover between a passive scalar regime at early times and a ...

Acute infection as a trigger for incident venous thromboembolism: Results from a population‐based case‐crossover study

open access: yesResearch and Practice in Thrombosis and Haemostasis, 2017
Essentials There is a bidirectional relation between acute infections and immobilization We studied the impact of infection and immobilization on risk of VTE in a case‐crossover design Acute infection was a strong trigger for VTE independent of ...

Loewner driving functions for off-critical percolation clusters

open access: yes, 2009
We numerically study the Loewner driving function U_t of a site percolation cluster boundary on the triangular lattice for ...

Density response of a trapped Fermi gas: a crossover from the pair vibration mode to the Goldstone mode [PDF]

open access: yes, 2011
We consider the density response of a trapped two-component Fermi gas. Combining the Bogoliubov-deGennes method with the random phase approximation allows the study of both collective and single particle excitations.

Superfluid density of states and pseudogap phenomenon in the BCS-BEC crossover regime of a superfluid Fermi gas

open access: yes, 2010
We investigate single-particle excitations and strong-coupling effects in the BCS-BEC crossover regime of a superfluid Fermi gas. Including phase and amplitude fluctuations of the superfluid order parameter within a $T$-matrix theory, we calculate the ...

Self-trapping of a Fermi super-fluid in a double-well potential in the BEC-unitarity crossover [PDF]

open access: yes, 2009
We derive a generalized Gross-Pitaevskii density-functional equation appropriate to study the Bose-Einstein condensate (BEC) of dimers formed of singlet spin-half Fermi pairs in the BEC-unitarity crossover while the dimer-dimer scattering length $a ...

Air Pollution and Emergency Department Visits for Depression: A Multicity Case-Crossover Study

open access: yesEnvironmental Health Insights, 2016
Background The aim of this study was to investigate the associations between ambient air pollution and emergency department (ED) visits for depression. Methods Health data were retrieved from the National Ambulatory Care Reporting System.

Does a functional prosection provide a more effective method of learning the anatomy of the forearm and hand than a 3D online anatomy resource?

open access: yesMedEdPublish, 2018
Recent changes to anatomy education across UK medical schools are thought to be contributing towards a lower proficiency in anatomical expertise amongst students. The introduction of alternative learning methods may help to overcome this. Prosections and
